The DNS map code in Sendmail 8.12.8 and earlier, when using the "enhdnsbl" feature, does not properly initialize certain data structures, which allows remote attackers to cause a denial of service (process crash) via an invalid DNS response that causes Sendmail to free incorrect data.

The prescan function in Sendmail 8.12.9 allows remote attackers to execute arbitrary code via buffer overflow attacks, as demonstrated using the parseaddr function in parseaddr.c.

Unknown vulnerability in NFS for SGI IRIX 6.5.21 and earlier may allow an NFS client to bypass read-only restrictions.

Unknown vulnerability in the NFS daemon (nfsd) in SGI IRIX 6.5.19f and earlier allows remote attackers to cause a denial of service (kernel panic) via certain packets that cause XDR decoding errors, a different vulnerability than CVE-2003-0619.

Heap-based buffer overflow in the name services daemon (nsd) in SGI IRIX 6.5.x through 6.5.21f, and possibly earlier versions, allows attackers to gain root privileges via the AUTH_UNIX gid list.

Unknown vulnerability in nsd in SGI IRIX 6.5.x through 6.5.20f, and possibly earlier versions, allows attackers to cause a denial of service (memory consumption).

The Name Service Daemon (nsd), when running on an NIS master on SGI IRIX 6.5.x through 6.5.20f, and possibly earlier versions, allows remote attackers to cause a denial of service (crash) via a UDP port scan.

Unknown vulnerability in SGI IRIX 6.5.x through 6.5.20, and possibly earlier versions, allows local users to cause a core dump in scheme and possibly gain privileges via certain environment variables, a different vulnerability than CVE-2001-0797 and CVE-1999-0028.

SGI IRIX 6.5.x through 6.5.20f, and possibly earlier versions, does not follow "-" entries in the /etc/group file, which may cause subsequent group membership entries to be processed inadvertently.

The DNS callbacks in nsd in SGI IRIX 6.5.x through 6.5.20f, and possibly earlier versions, do not perform sufficient sanity checking, with unknown impact.
